What are the 33 paths of masonry?

There are not 33 paths in Masonry. A "path" suggests a series of steps leading to a goal. The steps, if you like, in Masonry, are called degrees and are usually grouped in sequences. These sequences might be called paths, although they are not actually called that (they are more usually called "rites"). In the Scottish Rite there are 32 degrees including the three Craft degrees of Apprentice, Fellowcraft and Master. The governing body for the jurisdiction is called the 33rd degree. There are not 33 rites in Masonry even if you include some disused and discredited ones.
